He used safety pins.

Rating: 8/10 (28 February 2018)

Sound: Great sound effects editing. I did not like the way the theme song got used in the score, very weak, not developed enough.
70/100
Technical: Well done but with some minor problems, like bad background extra acting and some of the takes with the German actors were tinged with some bilingual confusion.
70/100
Narrative: Standard narrative of the first 24 hours of D-Day from many points of view; military, civilian, ally, enemy, fighting men, and support units.
90/100
Acting/Character: Excellent use of an ensemble cast. We feel for the soldiers and their comrades.
90/100
Did I like it: Yes, all of the merging story lines mixed with the humor and anti-war tone made it very enjoyable.
100/100
Artistic merit: I compare this film to Saving Private Ryan in subject and scale. Very few war films portray the different points of view in a battle.
80/100
Total score 83.3/100
